List of eletrocardiographic signs indicative of primary electrical heart diseases
| ECG signs . | Suspected disease . |
|---|---|
| Corrected QT interval >0.46 s | Long QT syndrome |
| Corrected QT interval <0.32 s | Short QT syndrome |
| Right bundle branch block with coved type/saddle type ST segment elevation in the right precordial ECG leads (V1–V3) either spontaneous or provoked by flecainide or ajmaline | Brugada syndrome |
| ε-wave and/or T-wave inversion with QRS duration >110 ms in the right precordial ECG leads (V1–V3); ventricular ectopic beats with left bundle branch block and right-axis deviation morphology | Arrythmogenic right ventricular cardiomyopathy |
| High voltage in the precordial leads, Q wave, ST changes | Hypertrophic cardiomyopathy |
